Abstract: This paper designs and implements a medical assist expert system based on object-oriented method. While designing the inference engine, some new concepts are defined according to the characteristic of medicine assist field, such as description edge, arbitration edge and arbitration path. And these concepts are used as heuristic information to reason, in order to gain more credible solution. The knowledge database and inference engine of the system are separate, so it is universal for medicine assist field.

Key words: object-oriented method, expert system, medical assist system, arbitration path
